P3D Re: Instant Lenticular Camera

Yep, that's why I was thinking of polaroids.  If such a thing were in mass
production you'd want film stock with the emulsion directly on the back of
the lenticular plastic.  For a one-off you'd have to have one sheet in the
camera and stick a matching one on afterwards.  You could get
enlargements, but only to a size that matches an existing grade of
plastic.  Less than ideal, and requiring great accuracy too.

According to Image Tech's web site you get one stripe of each image per
lenticule.  I guess that could be a simplified version of the truth, but
it wouldn't matter.  That bit should look after itself.

What did worry me was I wasn't sure that it wouldn't produce pseudoscopic
pics.  I *think* I've got the geometry sussed now though, and it would be
OK.
